Cops calling you a good samaritan?

Camsterguy

I've just read on the GTA Wiki that if you spawn an FIB Buffalo next to a cop who's just arrested an NPC, the officer will thank you for delivering a car for his use. Since the GTA Wiki isn't the most reliable source ever, I want to ask you guys if you've ever seen this?
I've been playing IV on PC since release and never seen this...
